Abdominal MRI (with contrast)

What it is

The abdomen is mostly solid organs of similar density, and an unenhanced image of the liver is largely a picture of uniform gray. Gadolinium is what gives that gray a structure. Injected into a vein, it arrives first through the arteries, then fills the tissue, then drains away, and organs and lesions differ in how they handle each of those phases — one area grabs the dye early and lets it go, another takes it up slowly and holds it. That behavior is often what identifies a finding rather than merely locating it. This code records a study imaged after contrast. Many abdominal protocols also run a full plain series first, as the baseline that makes the comparison possible, and those belong under the with-and-without code; if this code is what appears on your statement, it is fair to ask what was actually acquired.

Why it is done

• To look more closely at a spot found in the liver, pancreas, kidney, adrenal gland or spleen on an earlier ultrasound or CT
• To stage or follow a known cancer in the abdomen and to check for spread
• To assess the blood supply and drainage of the abdominal organs
• To investigate abdominal pain, swelling, or liver and kidney blood results that have not been explained
• To look at enlarged lymph nodes or a collection deep in the abdomen when infection is suspected

What to expect

Fasting for a few hours beforehand is common, both to settle the bowel and because the gallbladder is easier to assess when it has not emptied. An IV is placed and kidney function is usually checked before contrast is given. The distinctive demand of abdominal MRI is breathing: the organs shift with every breath, so many sequences are taken in bursts of ten to twenty seconds while you hold still and do not breathe, with the instruction coming through headphones. Practising a steady breath hold in the waiting room genuinely improves the images. Expect roughly forty-five minutes to an hour, and expect the machine to be loud.

Questions worth asking

• Ask whether the requisition covers the abdomen only or the abdomen and pelvis. That is two codes and two charges, and both frequently appear on the same order.
• Ask whether a bile and pancreatic duct series is included. That study carries its own code and is not part of this one.
• If this scan follows a CT or ultrasound done somewhere else, ask whether those images have been obtained for comparison rather than repeated.
• Abdominal MRI is one of the studies where hospital and freestanding prices diverge most sharply. Ask both, and ask whether a facility fee applies.
• Breath-holding studies are sometimes abandoned partway through. Ask what the facility charges for an incomplete or repeated scan.
